ENA/17/01 - ETR 140 - Statutory Voltage Limits at customers’ terminals in the UK and options for future application of wider limits at low voltage
TargetAudience: Technical Report 140 (ETR 140) will be of interest to designers of customer low voltage (LV) installations It will also be of interest to LV equipment and appliance manufacturers, designers and operators of LV distributed generation, electricity suppliers and electricity consumer groups.
Summary - In January 2015, an ENA Task Group was established to consider the findings of various Low Carbon Network Fund projects in relation to voltage control on the low voltage (LV) network. The Task Group reviewed the current lower bound of the statutory voltage limits on the LV network and specifically at LV customers’ terminals. The Task Group also reviewed the option for changing the current lower bound from 6 per cent below nominal voltage to 10 per cent below nominal so as to align with the current BS EN 50160 and BS EN 60038 standards. The report of the Task Group, ETR 140, sets out the positive and negative aspects of these proposed changes in policy and practice on network operators, customers, generators and other stakeholders in terms of planning and operations.
Because of the potential impacts, both positive and negative, on stakeholders, ETR 140 recommends that a consultation is undertaken to understand the wider views within the UK regarding voltage limits and a wider voltage range.
